LUNGS
:
lowest MLD: DIBH + BVMAT.
Lowest
V30, V25, V20
, V15: FVMAT + DIBH
while
V5, V10
is lowest with B VMAT + DIBH
HEART
:
lowest doses:
F-VMAT
+ DIBH with a significant
difference from FB plans.
B-VMAT
+DIBH doses were marginally higher but
the difference was
not
statistically significant
apart from
V15, V20
.
BREASTS
:
Best breast doses: B-VMAT + DIBH
Particularly
V4
